Got the Seidio cover today. It's nice overall. I can confirm, it does fit in the Droid2 docking station.
Pros: It feels really nice to touch. The dimensions are near perfect on it in relation to the microphones and speaker. The standard cover blocked the extra noise canceling mic on the back, which annoyed me to no end.
Cons: The back plate isn't 100% snug. Nothing to bad, but it does shift a little bit. Also, on the front, there is a slight lip that makes pressing the home buttons a little unnatural.
Again, nothing that would persuade against buying, but just an FYI to forum. It is definitely nicer than the $10 plastic cases available from Verizon. Hard to say if it is worth the 2.5X premium, but if you want a premium case for your phone, this case works nicely.
